What’s the key to cancer? Clue it’s not gene mutations.

There is a major flaw in our current theory about cancer: This says it’s caused by random genetic changes in a cell that allow it to grow uncontrollably and the only solution is drugs and surgery. This ignores, says a University of California professor, the many ways our bodies can encourage a tumour or block the gene changes driving it. If she’s right a new range of treatment possibilities opens up.
